Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, confident silhouette across the hand. This three-stone semi-set engagement ring in 18K rose gold frames a 12 x 6 mm marquise center with two delicate side stones, balancing modern minimalism with architectural clarity.

Each band is meticulously crafted in warm rose gold, polished to a soft glow that complements the diamond’s sharp geometry. The low-profile setting ensures daily wearability without catching, while the smooth comfort fit embraces the finger with subtle ease. Finished and inspected in our Williamsburg studio, this ring is designed for life’s quiet moments and bold declarations alike.

Our lab-grown diamonds offer the same brilliance and clarity as mined stones, with a fraction of the environmental impact—an ethical choice made without compromise.

The elongated marquise shape naturally elongates the finger, ideal for those seeking a ring that feels both striking and refined. Its three-stone design invites stacking or solo wear, versatile for a modern lifestyle.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit without delay.
